Platelet-Rich Fibrin (PRF) vs Bone Graft With Membrane for Ridge Preservation After Tooth Extraction
Application of Platelet-Rich Fibrin Consolidated Bone Substitutes in Alveolar Ridge Preservation: A Randomized Controlled Study
This study uses a natural material called Platelet-Rich Fibrin (PRF) to help improve healing after tooth removal. PRF is made from your own blood. A small amount of blood is taken from your arm and spun in a machine to make a thick, sticky layer full of platelets. These platelets help your body heal. PRF acts like a "natural bandage" and may help your gums and bone heal faster. Because it comes from your own body, it is safe and lowers the chance of infection or problems.
The goal of this research is to see if adding PRF to a bone graft (used to fill the tooth socket after extraction) can help the area heal faster and grow more new bone.
If you join this study, it will last about 4 months. You will have two teeth removed, and each socket will get a different treatment:
- One socket (test side) will get PRF + bone graft (this combination is also called "sticky bone").
- The other socket (control side) will get a bone graft + a covering called a barrier membrane (made of collagen).
We will compare how well the two sides heal by looking at:
- How the gums close over the area
- How much pain you feel
- How much the bone changes
- How much new bone grows You will come to the clinic for about 9 visits in total. These visits are part of your regular treatment, along with a few extra steps for the study.
One possible risk is bruising or soreness from the blood draw. If we cannot collect enough blood (about 60-80 ml) because your veins are too small or hard to find, you will not continue in the study, and both sockets will be treated using the control method (bone graft + membrane).

Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Sperimentale: PRF-solidified bone graft
Extraction socket is grafted with freeze-dried bone allograft (FDBA) mixed with autologous platelet-rich fibrin (PRF) to form a cohesive graft, without placement of a barrier membrane.
|
Autologous platelet concentrate prepared from the participant's blood and applied to the extraction socket, mixed with bone graft.

|
|
Comparatore attivo: Bone Graft With Collagen Membrane
Extraction socket is grafted with freeze-dried bone allograft (FDBA) and covered with a resorbable collagen membrane for ridge preservation.
|
Human-derived bone graft material used to fill extraction sockets for ridge preservation
Resorbable membrane placed over the grafted socket to stabilize the graft and prevent soft tissue ingrowth.

Cosa sta misurando lo studio?
Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Change in alveolar ridge dimensions
Lasso di tempo: 4 months after ridge preservation (prior to implant placement)
|
Change in alveolar ridge width and height will be measured by superimposing baseline and 4-month follow-up cone-beam computed tomography (CBCT) images at standardized cross-sectional locations corresponding to the extraction sites.
|
4 months after ridge preservation (prior to implant placement)
|
Misure di risultato secondarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Wound healing (re-epithelialization)
Lasso di tempo: 1, 2, 3, and 4 weeks after ridge preservation
|
Soft tissue wound closure over extraction sites will be assessed using serial intraoral scans and analyzed to quantify changes in wound area over time.
|
1, 2, 3, and 4 weeks after ridge preservation
|
|
Percentage of new bone formation
Lasso di tempo: 4 months after ridge preservation (at implant placement)
|
Bone core biopsies obtained at implant placement will be analyzed histologically to determine the percentage of newly formed bone within the grafted sites.
|
4 months after ridge preservation (at implant placement)
|
|
Crestal soft tissue thickness
Lasso di tempo: 4 months after ridge preservation (at implant placement)
|
Soft tissue thickness at the alveolar crest will be measured clinically using a periodontal probe at the time of implant placement.
|
4 months after ridge preservation (at implant placement)
|
|
Postoperative pain score
Lasso di tempo: 1, 2, 3, and 4 weeks after ridge preservation
|
Participant-reported pain will be assessed using a visual analog scale (VAS, 0-100), where higher scores indicate greater pain intensity.
|
1, 2, 3, and 4 weeks after ridge preservation
